Tegra264 has 17 generic I2C controllers, two of which are in always-on
partition of the SoC. In addition to the features supported by Tegra194
it also supports a SW mutex register to allow sharing the same I2C
instance across multiple firmware.
Document compatible string "nvidia,tegra264-i2c" for Tegra264 I2C.
